Vancouver, British Columbia – March 12, 2026 - TheNewswire - Leocor Mining Inc. (the “ Company ” or “ Leocor ”) (CSE: LECR, OTCQB: LECRF; Frankfurt: LGO0) (formerly Leocor Gold Inc.), a junior resource company focussed on the exploration and development of precious metals  projects in Eastern Canada, is pleased to announce it is planning a VTEM Survey (the “ Survey ”) at the Company’s 2,002-ha contiguous Baie Verte gold-copper exploration project.  The Baie Verte project (the “ Project ”) is situated on the north central coast of the island of Newfoundland in the province of Newfoundland and Labrador, Canada.

The Survey will cover the entire project area and will generate critical informative data the Company will utilize to assess and determine primary targets for follow-up drilling.  Last summer's drill program identified a VMS style mineralizing system within the Copper Creek section of the Baie Verte project (see News Release dated July 8, 2025). The fundamental premise of applying electromagnetic (EM) methods to VMS exploration is the strong conductivity contrast between the massive sulphide mineralization and the surrounding host lithologies.

“We’re eager to get follow up drilling completed at Baie Verte,” said Alex Klenman, CEO of Leocor Mining.  “The discovery of VMS style mineralization last year was significant and the case to continue drilling, particularly at Copper Creek, is certainly compelling.  The survey will aid greatly in prioritizing drill targets as we move forward with the development of the Baie Verte project,” continued Mr. Klenman.

VMS deposits are syngenetic accumulations of sulphide minerals that form through hydrothermal discharge in submarine volcanic environments, typically occurring as lenses of polymetallic massive sulphide. These systems are characterized by two primary components: a stratabound lens containing over sixty percent sulphide minerals and an underlying discordant stringer or stockwork zone composed of vein-type mineralization within an envelope of altered rocks. Both intersected in last year's drill program.

The electromagnetic signature of a VMS deposit is primarily a function of its mineralogical composition and the connectivity of conductive grains. Common sulphide minerals such as pyrite, pyrrhotite, and chalcopyrite possess extremely high electrical conductivity, often resulting in orebodies with very low resistivities compared to host rocks like rhyolites, andesites, or sedimentary sequences. This contrast can span up to five or more orders of magnitude, providing ideal conditions for the induction of eddy currents during a time-domain EM survey.

The VTEM system operates on the principle of time-domain electromagnetic induction. A transmitter coil, carried by a helicopter, generates a primary electromagnetic field by passing a powerful current through a large loop. In VTEM, this current follows a triangular ramp or polygonal waveform that is rapidly terminated. The collapse of this primary field induces eddy currents in any nearby conductive bodies in the subsurface, such as a massive sulphide lens. These induced currents generate a secondary magnetic field that decays over time. VTEM measures the time rate of change of this secondary field using induction coil receivers during the "off-time" between transmitter pulses.

More details will be provided once the survey dates are finalized.
